This session is designed to improve understanding and application of recent updates to synoptic pathology reporting protocols such as the latest Reporting Template for Reporting Results of Biomarker Testing of Specimens from Patients with Carcinoma of the Breast. These changes reflect evolving clinical guidelines that directly influence diagnostic accuracy and treatment selection in breast cancer care.

Webinar presenters Thaer Khoury, MD, FCAP, Chair, Pathology and Laboratory Medicine, Roswell Park Comprehensive Cancer Cente, and Colin Murphy,  CEO of mTuitive.

In this webinar, we will examine how immune recognition after allogeneic HCT can influence leukemia relapse and disease progression. The session will highlight the clinical relevance of HLA loss of heterozygosity (LOH), approaches used for its detection, and how LOH findings may support transplant strategies, including considerations for donor selection in subsequent transplantation.

Webinar presenter Alberto Cardoso Martins Lima, PhD, Clinical consulting scientist in histocompatibility,
specializing in allogeneic hematopoietic cell transplantation (HCT) at IGEN/AFIP São Paulo and CHC/UFPR in Curitiba, Brazil

Anatomic pathology selected abstracts

April 2023—Kaposi sarcoma can pose diagnostic challenges in biopsy specimens. Multiple histologic variants of cutaneous Kaposi sarcoma (KS) have been described. However, the histomorphologic spectrum of gastrointestinal KS has not been systematically studied. The authors presented a large multi-institutional case series that comprehensively evaluated 46 cases of KS involving the GI tract and identified seven histomorphologic variants, some of which had not previously been described. Five of the variants—lymphangioma/lymphangiectatic like (n=17), mucosal hemorrhage/telangiectatic like (n=17), mucosal inflammation like (n=15), granulation tissue like (n=13), and mucosal prolapse like (n=4)—were inconspicuous but had unique morphologic patterns. These variants easily can be misdiagnosed or misinterpreted on routine examination if KS is not considered and if the IHC stain for human herpesvirus-8 is not utilized.

 

Molecular pathology selected abstracts

April 2023—Clonal hematopoiesis of indeterminate potential refers to the clonal expansion of hematopoietic stem cells that harbor a somatic mutation in people who do not exhibit hematological symptoms. This phenomenon is common in the elderly and associated with an increased risk of hematological malignancies, cardiovascular disease, infection, and all-cause mortality. Several somatic alterations are frequently detected in clonal hematopoiesis of indeterminate potential (CHIP), but the medical community’s understanding of the underlying genetic predisposition to CHIP is limited. The authors conducted a large-scale exome-sequencing study involving more than 600,000 people to characterize CHIP status and discover rare somatic variants and possible predisposing germline alterations. The prevalence of CHIP was 15 percent by 75 years of age, and the affected individuals were more likely to be heavy smokers, in agreement with previous studies.

 

Q&A column

April 2023
Q. Which criteria should be used to interpret mixing studies, not only for lupus anticoagulants but also for other inhibitors? Read answer.
Q. How does the CAP checklist requirement COM.30840 Pipette Carryover relate to blood bank automation? Are there CAP guidelines that address pipette carryover relative to such systems? Read answer.
Q. Our laboratory is assessing criteria for determining quantity not sufficient for a microscopic urinalysis. We were using an automated instrument but have gone back to manual microscopy for reasons beyond our control. While most textbooks state that 10 to 15 mL is the desired amount of sample for testing, it appears that many laboratories require smaller amounts. Can you provide guidance? Read answer.

April 2023—At the medical center of the University of Medicine and Pharmacy at Ho Chi Minh City, patients are not screened for bladder cancer using urine cytology because the pathology department does not have the capability for such screening. But that may soon change, thanks to an organization focused on using digital pathology to increase the availability of pathology education resources in developing countries.

Put It on the Board

April 2023—Abbott has received FDA clearance for its Alinity i TBI laboratory test for traumatic brain injury. The test provides a result in 18 minutes to help clinicians assess concussion and triage patients.

Letters

April 2023—There have been several recent articles in CAP TODAY regarding the use of whole blood and prehospital transfusion. The general tenor of the reporting has supported these novel practices. We would like to suggest an alternative perspective.
